GIS Metadata

Description: All current, active business licenses

Process: Data is queried from TRMS, processed to clean up common addressing issues (change "FT LOWELL" to "FORT LOWELL" - street name "1" become "1ST", funny "ÿ" characters are removed etc) and geocoded. Geocoding is a 3 step process:

1 - whole table is geocoded to adparcel with a 9.3.1 geocoder (scores of 69 and higher become seperate layer)

2 - anything with a score of 68 or below is joined to adparcel based on street #, street direction and street name - those that have a match have their address recalculated based on the full address in adparcel and are geocoded again with the 9.3.1 geocoder (become seperate layer)

3 - those from step 2 that do not have a match in adparcel are goecoded to stnetall and everything with a score of 80 or above are exported out as a seperate layer

Layers from steps 2 and 3 are appended into layer in step 1 and the original buslic FC has records deleted and the new data appended.

Known Errors:

All locations are approximate. Most data is mapped to existing address points (which are not precise locations),

those records that don't have an equivilant address match are approximated along the address range of street. See

MT field for more details.

Fields for NAICS codes, business types and owner types may be missing data or incorrect.

Data layer should not be considered a complete listing of all active businesses in Tucson.
